Clinical trials: Overlap Syndrome
Asthma-COPD Overlap Syndrome
This Study Include Asthma Chronic Obstructive Pulmonary Disease (COPD) Overlap Patients.Patients Were Vitamin D Deficient.Age Range 40-70 Years, Smokers.Patients Were Advised to Take Either Placebo or Vitamin D3.Lung Functions and Exercise Tolerance Were Assessed at Baseline and at 26th Weeks.
Vitamin D3 supplementation doen not change lung functions and exercise tolerance in vitamin D3 deficient ACO patient was the null hypothesis of the research.
